This cut No 7 should finish the part of fixing the parsing of the events :
- Event_timed is no more used during parsing. Less problems because it has
a mutex. Event_parse_data class is used during parsing. It is suited only
for this purpose. It's pretty lightweight
- Late checking of data from parsing is being performed. This should solve
the problems of nested events in SP or other events (for the situation
of no nested bodies). Before if an ALTER EVENT was in a SP, then when the
SP was compiled, and not executed, the actual init_xxx methods of Event_timed
were called, which is wrong.
- It could be a side effect of using a specialized class, but test events_stress is
now 25% quicker.
Cut No8 will start splitting Event_scheduler into 2 parts, the QUEUE will be moved
to Event_queue.
mysql-test/r/events.result:
update result
mysql-test/t/events.test:
disabled is actually wrong, should be disable, but because of the early
checking it was never parsed.
sql/event_data_objects.cc:
move add init_xxx methods from Event_timed to Event_parse_data
Event_parse data does not need definer_user and definer_host
in Event_timed::compile() do not use lex.et, well there is no more lex.et :)
sql/event_data_objects.h:
move parsing responsibilities from Event_timed to Event_parse_data
sql/event_db_repository.cc:
No more Event_timed comes from parsing but Event_parse_data
The initialization of Item*-s from parsing is done late, and not
during the actual parsing. This is the right way to go because
if an ALTER EVENT is inside a SP or CREATE EVENT it should not be
executed (initialized) during parsing, as it was done.

sql/sql_lex.cc:
lex->et_compile_phase and lex->et are no more.
Use lex->event_parse_data
sql/sql_lex.h:
lex->et_compile_phase and lex->et are no more.
Use lex->event_parse_data
sql/sql_parse.cc:
lex->et_compile_phase and lex->et are no more.
Use lex->event_parse_data
ACL checks were moved inside the Events subsystem.
Also ending of the transaction is performed only just
before doing disk operation. Therefore only when needed.
sql/sql_yacc.yy:
lex->et and lex->et_parse_phase are no more
Use the specialized for parsing Event_parse_data
5th cut, moved DB related code to Event_db_repository and
updated accordingly the remanining code.
Moved change/restore_security_context() to class THD
Removed events_priv.h
Next step is to reorganize create/update_event() and parsing for them.
But probably some other refactoring could be done in the meanwhile.
The changes so far pass the test suite.

Second cut of separating parsing phase from execution phase
Separate Event_timed from parsing phase and introducing Event_parse_data.
sql/event_data_objects.cc:
second cut,
copy Event_timed::init_body() to Event_parse_data::init_body()
Init the body during parsing, everything else keep as a pointer to
Item or some other pointer to use for later initialization.
sql/event_data_objects.h:
get the identifier as sp_name*, later will initialize our structures
sql/events.cc:
for easy transition add temporarily parse_data, later Event_timed *et will be removed.
Do slow transition because Event_timed is so tightly integrated that a front-attack
by removing things from this class was unsuccessful. Do things step by step by eliminating
dependencies. Hence, the code could be checked with the current test suite too
(early testing)
